Specification of Letters I Patent Patented Dec. 29, 1908.

Application filed September 14-, 1908. Serial No. 462,824.

To all whom it may concern: Y

. Be it known thatI, DANIEL A. SPRAGUE of Poland, in the county ofHerkimer and State of New York, have invented certain new and usefulImprovements in a Combined Churn and Butter-Worker; and I'do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

The object of my present invention is to provide a combined churn andbutter worker, which is simple in construction, efiicient in operation,easily operated, easily cleaned and reasonable in cost of construction.

Figure 1 shows an end view of my present machine, with a section brokenaway: to re.-.

duce the size of the figure. Fig. 2 is" a longitudinal sectional view ofthe same. Fig. 3 is a cross sectional view through the body.

Fig. 4 shows the opposite end from that shown in Fig. 1.

Referring to the reference figures in a more I particular'description,10 indicates the body of the churn, which is of cylindrical form, havingheads in each end and all together forming a receptacle mounted onjournals 11 and 40 in the standards ofthe frame 13 for rotation, Thebody is provided with an opening through which access may be had to Ithe interior for the purpose of introducing the cream, salting,inspecting and removing the butter and washing and cleaning the interiorof the rece tacle with its accessories. The 0 ening is a apted to beclosed by a remova le cover 14. For rotating the body on its horizontalaxis, the journal 11 is extended and provided with a crank 15. Forrotating the body more slowly and with greater power a gear pinion 8 isprovided with a s ort shaft mounted in a'bearing on the standard of theframe and meshing with a gear wheel 9 provided on the body end andpreferably ma e integral with the journal ase plate. The crank 15 may betransferred from the journal 11 to the shaft carrying the pinion 8.-

Extending longitudinally through the body on the axle e and in the lineof the journals 11 and 40 is a shaft 16 incased and provided with a setof substantiall radial projecting fingers 18, all toget er constitutingthe worker 17. The fingers 18 are member 30".

well spaced and relatively narrow as com-' pared with the space, andpreferably disposed as to their secured ends on both'sides of the shaft16, whereby they are somewhat offset with reference to one another, butall projecting in the same general radial direotion from the axis on oneside of the axis of the churn body. The shaft 16' with its fingersconstituting the-worker is rotatable in dependently of the body of thechurn, and at one end has a bearing in and extends through the journal40, and at the other end has a bearing at the base of the journal 11,but preferably does not extend through.

For controlling the worker there is provided a hand wheel 30 mounted onthe externally extended end of the worker shaft 16, preferably by beingprovided with a square ole receiving a square section of theworkershaft, whereby the hand wheel is held front rotation with referencetothe shaft; but the arrangement is such that the hand wheel may be movedlaterally along the shaft a limited distance. The hand wheel 30 isprovided at one end with clutch teeth or clutch member 30*, and at theother end with another clutch The clutch member 30 is adapted, when thehand wheel is shifted in the roper direction, to engage with clutch memer 40- on the end of the journal 40,

thereby securing the worker to the body for rotation therewith. I

.4 At the outer end of the shaft 16 there is rozided a stationary orfixed clutch member 41 supported and held by an arm 42 from the frame.When the hand wheel is shifted in the proper direction, the clutchmember 30*- of the wheel may be engaged with the stationary clutchmember 41, whereby the worker is held against rotation while the body isadapted to be freely rotated. The arrangement of the hand wheel andclutch members is also such that there is an intermediate position forthe hand wheel when both clutcheswill be out of engagement, at whichtime the worker is under independent manual control by the hand wheel.The hand wheel has a set screw 37 by means of which it may be secured inany of its several positions of ad'ustment along the shaft 16.

Within the ody the churn is prozided with a set of inwardly projectingfin are 25, which are rigidl secured m the walof the body and exten Inearly to the axial line in a radial direction, if desired, butpreferably with a somewhat forward 1 inclination as shown in thedrawings. The set of body} posed with reference to those of the worker,

so as to pass through the middle of the spaces between the workerfingers when they are relatively rotated with liberal clearance spacebetween when passing. I

The clutch members and 10 will preferably be soarranged that they can beengaged only in one position, and, further, the arrangement willpreferably be such that this engagement can only be made when the workerfingers are interposed or interpositioned with the body fingers.

For churning, the combined body and worker fingers constitute a singledasher. In churnin the body should not be filled more than ha full ofcream. In the revolution the dasher strikes down on the surface of thecream, rakes through the body of the cream, and then passes above thesurface, afiording ample time for the cream to become settled beforerepeating the operation. The clearance between the fingers, even wheninterposed,

allows the cream to pass through quite freely. With what might perhapsbe considered too rapid a rotation of the churn in churning, the creammight be carried up or forward by the dasher, in which case it would bepoured over the shaft and the fall would be effective in churning.

The churning is preferably stopped when the butter has come in granularform (as to be noted through a glass covered hole),

' and the butter milk drawn off and the butter ber 41.

washed and salted. While drawing off the butter milk and salting thebutter, the hook 21 may be engaged with the eye 22 to secure the bodyagainst rotation. For the purpose of workin the butter, the position ofthe hand whee 30 will be shifted so as to engage the clutch member 30with the clutch mem- These clutch members are arranged preferably to beca able of engagement only in one position, an that preferably with'theworker fingers 18 on a downwardly inclined angle, as shown in Fig. 3 ofthe drawings. The worker being set, that is to say, secured in astationary position and the body of the churn rotate in the direction ofthe arrow shown in Fig. 3, preferably by means of the crank 15 apbpliedto the inion 8, the butter is gathered etween the fiiigers 25 and 18 anda portion forced through the fingers 18, while a portion escapesbackwardly through the r fingers 25, effecting a squeezing and break 1 B5 ing or cutting operation, constituting effective sosnea working. Theportion of the butter which passes through t e fingers 18 is carriedahead of the fingers 25 until it is dumped over the shaft 16 and it,together with the butter that has passed backwardly through the finers25, is gathered and massed and again forced through the fingers 18 withthe next revolution.- A few revolutions of. the churn body when thus 0erating will produce a sufficient working. en the Workin has beencompleted, the worker will prefers ly be returned to its former positionwith the fingers 18 and 25 interposed and secured in that position. Thechurn now being revolved the more or less broken body of butter will beathered ahead of the combined fingers and umped over the shaft. .A fewrevolutions in this operation will mass and packthe but- 1 ter in asingle body and in a desirable condition to 'be removed from the churn.

The offset position of the fingers 18 on the worker, or the offsetosition of the fingers 25 on the body if emp oyed, enable the churn towork butter with the a plication of somewhat less power than t ough eachset of fingers were arranged in a single plane, for obvious reasons. Theoffset position of the fingers when combined to constitute a dasher alsoforms a dasher which affords larger pas-- sages for the cream betweenthe fingers, which in some views of the matter is an advantage.

Churns require very careful cleaning, for

which purpose ready access is desirable to all interior parts. Inwashing and cleaning this combined churn and butter worker, the handwheel 30 will be adjusted to its intermediate position, placing theworker readily under the control of the operator and allowing it to bepositioned to afford access to all of its arts, and to remove it fromany position w iich would prevent ready access to the body fingers andall parts of the interior. of the body.

It is evident that other modifications and changes in and from theconstruction herein described may be made without departing from theinvention hereinafter pointed out and intended to be claimed in theclaims.

.What I claim as new and desire to secure by Letters Patent is:

1. The combination of a churn body mounted on journals to be rotated onits horizontal axis and having a longitudinal row of. inwardly rojectingfingers on one side of the axis 0 y, and an axially mountedindependently rotatable worker within the body having a single set ofoutwardly projecting fingers arranged along one side and to operatethrough the spaces between worker with its fingers in set position andmeans for securing the worker with its fingers to the body for rotationtherewith, substantially as set forth.
